Sampling Of Sterogram Images

I found these on Stumbleupon one day and it really changed my opinion of stereograms. After viewing the underwater ones that follow I found the terrain picture that is above. According to Wikipedia the deffinition is as follows…..

stereogram is an optical illusion of depth created from flat, two-dimensional image or images. Originally, stereogram referred to a pair of stereo images which could be viewed using stereoscope. Other types of stereograms include anaglyphs and autostereograms.

Stereogram was discovered by Charles Wheatstone in 1838. He found an explanation of binocular visionwhich led him to construct a stereoscope based on a combination of prisms and mirrors to allow a person to see 3D images from two 2D pictures.

Stereograms were re-popularized by the creation of autostereogram on computers, where a 3D image is hidden in a single 2D image, until the viewer focuses the eyes correctly. The Magic Eye series is a popular example of this. Magic Eye books refer to autostereograms as stereograms, leading most people to believe that the word stereogram is synonymous to autostereogram.

Salvador Dalí created some impressive stereograms in his exploration in a variety of optical illusions.

The effect does wonders to the fish and environment in the deep sea photos. To look at these excellent underwater stereograms you must go from staring straight and then crossing yor eyes. That middle spot is where the magic happens. Sort of like adjusting the lens to make the picture clear in a photo. Once you start to see something try to concentrate and focus on just that image, it really brings it out. It trully is quite a quest to explain to others on how to do it. I only hope this helped some to experience a really cool effect and go and find some more stereograms for themselves.
